Incremental migration of lists

The On Demand Migration for SharePoint service can migrate new and updated list items in previously migrated lists with the content state migrated.

NOTE: Incremental migration of system libraries like Site Pages is not supported. These libraries are always fully re-migrated.

To trigger an incremental migration of a SharePoint list:

  1. Open the SharePoint contents tab and locate the SharePoint list. There are a couple ways to do this:
    1. Add a filter to show only objects of type list.
    2. Add a filter to show only lists with content state migrated.
  2. Select the list. You can check multiple lists to migrate multiple lists.
  3. Click MIGRATE

Repairing lists with migration issues

The On Demand Migration for SharePoint service can repair lists with the content state Migrated with Issues. See . When such a list is migrated, the contents of the list in the source and target tenants are compared. Missing items in the target are restored and items that are updated in the source since the previous migration will be incrementally migrated.

Lists are migrated based on the migration state. You can select multiple lists with different content states and the lists will be migrated based on its state. For example, an incremental migration will occur if new list items were added to a source list that was previously migrated, a repair migration will occur if the list was migrated with issues, and a full migration will occur for lists that have not been migrated.

To repair a list with migration issues:

  1. Open the SharePoint contents tab and locate the SharePoint list as described below:
    1. Clear all filters and search criteria Add a filter to show only objects of type List.
    2. Add a filter to show only objects where Type = List and Content State = Migrated with Issues.
  2. Select the list. You can select multiple lists if needed.
  3. Click MIGRATE. The New Migration Task wizard starts.
  4. Step 1: Options
    1. Specify the information as described below:
      1. Map unmatched users to - enter the Office 365 email address of an existing user in the target tenant.
      2. Include child structure and content - select this option if the list has any hierarchical items that you want to migrate.
      3. Clear selected SharePoint objects from the target before starting the migration - if this option is selected, a full migration will occur because the target list will be deleted and the existing migration state will be ignored.
    2. Click Next.
  5. Step 2: Version Options
    1. Select from the following options:
      1. Migrate most recent version only
      2. Migrate two most recent versions
      3. Migrate more versions (with options) - you must specify additional criteria if you select this option.
    2. Click Next.
  6. Step 3: Schedule

      1. Run now - the task will run immediately.
      2. Run later - the task will start after a time delay.
      3. Schedule - specify a future date and time.
    2. Click Next.
  7. Step 4: Summary
    1. Verify the task settings.
    2. Click Next.
